Wide-angle head-up display

Abstract

The wide-angle Head-Up display design allows the increase in horizontal peripheral field of view and is based on two, three or more unified informational channels with each of them containing axis-symmetric lens collimating optical system and visualizer comprised of more than one LCD-projectors with each of them containing LCD-matrix and tricolor illuminator, projection lens and integrated for all projectors the transparent-diffusive screen intended for representation of primary images and is located at the object-side focal plane of channel collimating optical system and moreover the primary images are located on the screen so that their adjacent horizontal boundaries are stitched with small overlap in order to ensure the uninterrupted representation of resulting image. The channels' axes are horizontally shifted relative to each other so that adjacent boundaries of peripheral fields of view for the neighboring channels are coincided.

1 . Wide-angle Head-Up display containing two-component mirror composed of two semitransparent mirrors that are moved apart and mutually parallel and informational channel containing axis-symmetric lens collimating optical system and visualizer generating primary image at object-side focal plane of optical system whereas in order to increase horizontal full and instantaneous fields of view display is supplemented by single or two similar informational channels with their axes shifted horizontally so that adjacent vertical boundaries of neighboring channels' peripheral fields of view are overlapped and a Head-Up display's full peripheral field of view is equal to a sum of two or three channels' peripheral fields of view respectively. 
     
     
         2 . Wide-angle Head-Up display by Cl.  1 , whereas in order to ensure stitching of vertical boundaries of informational channels' peripheral fields of view (for display with two similar channels) axis of left and right channels are horizontally shifted to the left and to the right relative to Head-Up display vertical symmetry plane by an angle that is equal to the half of full peripheral field of view horizontal size for a single informational channel. 
     
     
         3 . Wide-angle Head-Up display by Cl.  1 , whereas in order to ensure stitching of vertical boundaries of informational channels' peripheral fields of view (for display with three similar channels) axis of the middle channel is coincident with display vertical symmetry plane and axes of left and right channels respectively are shifted horizontally to the left and to the right relative to display's vertical symmetry plane by the angle that is equal to horizontal size of full peripheral field of view for single informational channel. 
     
     
         4 . Wide-angle Head-Up display by Cl.  1 , whereas in order to increase resolution and brightness of generated image it is carried out with visualizers containing two or more similar LCD-projectors and each of them is provided with LCD-matrix (with its long side located parallel to display horizontal axis) and illuminator, projective objective and installed at object-side focal plane of a channel collimating optical system, transparent-diffusive screen that is integrated for all projectors and intended for primary images representation and at the same time:
 ratio of the area of primary images generated by each LCD-projector and the area of the resulting image on the screen is inversely proportional to the number of LCD-projectors that are used for visualizer;   primary images are located at the screen so that their adjacent horizontal boundaries are stitched with small overlap (several pixels).   
     
     
         5 . Wide-angle Head-Up display by Cl.  4 , whereas in order to provide the generation of multicolored image it is carried out with LCD-projectors containing tricolor illuminators.
